I went for a pap smear three weeks ago and it was my first one, the nurse also done a swab test as she said there was a build up of Vaginal Discharge . My swab result came back and said I had BV and I was put on Metranizadole - 1 x 3 times daily 400mg. Since I have finsihed the course I have had lower abdominal pain and pain during intercourse . I am twenty and had the same sexual partner for over 2 years now.
